Got it. Thank you. I thought there was just a shutter under there somewhere and not an actual valve. lol.. I heard that clinking noise so I assumed it was a shutter of some kind.

I never thought to put it in recirc mode. I will have to try that. I usually never do because it causes the windows to fog up in every car I have owned.
